The people who think it was justified tend to say that:
- If it was Mexico who had attacked, the camp would be for Mexicans
- The World War 2 was a total war and governments were doing whatever it took to win the war, hence Pearl Harbor and also the atomic bomb.
- Considering how scary World War 2 was, it was just a matter of time until Americans would go paranoid about Japanese spies
The counter arguments are usually:
- America was doing the same thing that it was said to be fighting against
- It was not fair to the families
- Those were also american citizens and the xenophobia is unjustified
- It was a violation of the constitution
- It was morally wrong
